How do I get to the design page. The page that shows what the camera shows. I did it with the first test print but it was after setting up my GF.
From now on, how do I get there. I just put in a piece of PG draft board with stars drawn and a screen didn’t pop up or anything.

I can’t claim that, but I have only used it once to match a paper tracing for hole layouts and shape of a piece I just didn’t want to get all the measurements, slap it into Inkscape and export out the SVG.

That’s cool. As long as you understand that the output from GIMP is essentially an image. Lines have thickness. If you want to engrave you are good. If you need to cut then somewhere the drawing of a line needs to be converted to a vector with zero thickness.
